I always thought that institutionalized speeding would be very successful both in terms of additional revenues and time saved. Right now highway speed limits are set to a sort of common denominator: safest for the worst car and driver on the road. But if you're driving a modern, well-maintained car and are adequately trained, there's no evidence that you'd be unsafe driving 20 mph over the speed limit. So, why not for an extra, non-nominal, fee, raise speed limits on interstate highways to qualified drivers? Of course they'd have to take additional driving lessons, pass extra driving tests to extend their privilege every year, and drive only approved cars, i.e. no 1996 Ford Explorers need apply.
